Between the no-fee Bilt Mastercard and the AUD 550 Bilt Palladium sits the Bilt Obsidian Card at AUD 145 per year — and for a surprisingly large cohort of Australian renters, it is the programme’s genuine sweet spot, combining a materially better earning rate on rent than the free card with an annual fee low enough that you do not need to travel frequently to justify it. The Obsidian occupies a narrow but well-designed niche: renters who want more than 1 point per dollar on their largest monthly expense but cannot justify the Palladium’s AUD 550 fee. This article analyses the Obsidian’s earning structure, compares it against both its Bilt siblings and the broader Australian mid-tier card market, and evaluates how the incremental points it generates can be deployed for peak-season award bookings — the redemption challenge that most frustrates Australian frequent flyers.
The Bilt Obsidian Card at a Glance
The Bilt Obsidian Card carries a AUD 145 annual fee with no supplementary cardholder fee. The earning structure is a midpoint between the no-fee Bilt Mastercard and the Palladium.
Rent payments earn 1.5 Bilt Points per Australian dollar, up from the free card’s 1 point and below the Palladium’s 2 points. The rent earning cap remains 50,000 points per calendar year, meaning the Obsidian lets you hit the cap with AUD 33,333 of annual rent rather than AUD 50,000. For a Sydney renter paying AUD 750 per week — AUD 39,000 per year — the Obsidian captures the full 50,000-point rent allowance where the free card would earn only 39,000.
Dining earns 4 Bilt Points per dollar, up from the free card’s 3 and below the Palladium’s 5. Travel earns 3 Bilt Points per dollar, up from 2 on the free card and below 4 on the Palladium. All other purchases earn 1.25 Bilt Points per dollar, up from 1 on the free card and below 1.5 on the Palladium. On Rent Day, the first of each month, all multipliers double with a monthly bonus cap of 15,000 points — between the free card’s 10,000 and the Palladium’s 25,000.
The Obsidian includes no travel credit, no lounge access, and no travel insurance — it is strictly a points-earning card. This keeps the annual fee low and makes the card purely about the mathematics of incremental points versus incremental cost.
The Break-Even Analysis: Obsidian vs No-Fee Card
The Obsidian costs AUD 145 more than the free card per year. The question is how much additional spending is required to generate AUD 145 of incremental value through higher earning rates.
For the Australian renter spending AUD 12,000 on dining, AUD 8,000 on travel, AUD 5,000 on other purchases, and AUD 39,000 on rent, the free Bilt Mastercard generates 39,000 rent points at 1x (below the 50,000 cap because AUD 39,000 is less than the AUD 50,000 cap ceiling), 36,000 dining points at 3x, 16,000 travel points at 2x, and 5,000 other points at 1x. Adding the 10,000-point Rent Day bonus, the annual total is 106,000 Bilt Points.
The Obsidian on the same spend generates 50,000 rent points at 1.5x (hitting the cap exactly at AUD 33,333 of rent, and the remaining AUD 5,667 of rent beyond the cap earns nothing), 48,000 dining points at 4x, 24,000 travel points at 3x, and 6,250 other points at 1.25x. Adding the 15,000-point Rent Day bonus, the annual total is 143,250 Bilt Points — a gain of 37,250 points over the free card.
At a conservative redemption value of 2.5 cents per point for international business class, 37,250 additional points are worth AUD 931. Against a AUD 145 incremental fee, that is a return of 6.4 times the cost — an outstanding value proposition that requires no change in spending behaviour.
For renters spending AUD 30,000 or more on annual rent, the Obsidian’s 0.5-point-per-dollar rent earning advantage alone generates 15,000 additional points, worth approximately AUD 375 at 2.5 cents per point. That more than doubles the AUD 145 fee before accounting for the dining and travel earning uplifts. The Obsidian pays for itself on rent earning alone for any renter paying more than AUD 11,600 per year — essentially every renter in Australia.
Obsidian vs Palladium: When the Jump Is Not Worth It
The Obsidian’s value proposition is clearest when compared against the Palladium. The Palladium costs AUD 405 more per year on a gross basis — AUD 550 versus AUD 145 — or AUD 5 more on a net basis if you can fully use the Palladium’s AUD 400 travel credit.
On the same spending profile, the Palladium generates 50,000 rent points at 2x (hitting the cap), 60,000 dining points at 5x, 32,000 travel points at 4x, and 7,500 other points at 1.5x, plus a 25,000-point Rent Day bonus, for a total of 174,500 Bilt Points. That is 31,250 points more than the Obsidian. At 2.5 cents per point, the incremental points are worth AUD 781.
If you can use the Palladium’s AUD 400 travel credit, the net incremental fee is AUD 5, and the AUD 781 in incremental points represents an outstanding return. If you cannot use the credit — because you do not travel in a given year — the net incremental fee is AUD 405, and the return drops to 1.9 times the cost, which is still positive but less compelling.
For Australian frequent flyers who travel at least once per year and can use the AUD 400 travel credit, the jump from Obsidian to Palladium is mathematically justified. For those who travel infrequently or prefer to minimise annual fees, the Obsidian is the better value. The Obsidian occupies the sweet spot for renters who want meaningfully better earning than the free card without the commitment of a AUD 550 fee that requires travel to fully offset.
Deploying Obsidian Points for Peak-Season Award Availability
The incremental points generated by the Obsidian are most valuable when deployed for peak-season award bookings — December school holidays, Easter, and the June-July Australian winter escape window — where cash fares are at their highest and award seat availability is at its scarcest.
A family of four travelling from Sydney to Bali during the December school holidays faces cash fares of AUD 1,200 to AUD 1,800 per person in economy, or AUD 4,800 to AUD 7,200 total. A Velocity Points redemption on Virgin Australia or a partner airline for the same dates costs 28,000 Velocity Points plus AUD 80 in taxes per person one-way, or 112,000 points return for the family. The Obsidian’s 37,250 incremental points represent one-third of the total points required for that family holiday — a tangible, high-value redemption that the free Bilt Mastercard would take an extra year of spending to accumulate.
Peak-season award booking requires advance planning. For the December 2026 school holidays, Velocity and Qantas release award seats approximately 330 days before departure — early January to early February 2026. By the time July 2026 arrives, most peak-season award space on popular routes is gone. The Obsidian cardholder who has been earning at the elevated rate since January is better positioned to book at the 330-day window than the free-card holder who needs more time to accumulate the same points.
Who Should Not Get the Obsidian
The Obsidian is not the right card for two profiles. First, if you are a homeowner who does not rent, the Obsidian’s rent earning advantage is irrelevant, and the free Bilt Mastercard’s dining and travel earning rates — 3x and 2x — are close enough to the Obsidian’s 4x and 3x that the AUD 145 fee is not justified by the non-rent earning uplift alone. The incremental 10,000 to 15,000 points from higher dining and travel rates on an annual spend of AUD 20,000 are worth AUD 250 to AUD 375 at 2.5 cents per point, against a AUD 145 fee — positive but marginal, and not worth the application if you already hold the free card.
Second, if your annual rent exceeds AUD 33,333, the Obsidian’s rent cap of 50,000 points limits the rent earning advantage. A renter paying AUD 1,000 per week — AUD 52,000 per year — would earn 50,000 rent points on the Obsidian at 1.5x and 50,000 rent points on the free card at 1x (both hitting the cap). The rent earning advantage evaporates entirely, and the only incremental points come from the dining and travel earning uplift. At that rent level, the Palladium’s 2x rent rate is the only way to extract additional points from rent.

FAQ
Q: Can I upgrade from the free Bilt Mastercard to the Obsidian, or do I need to apply separately? A: Bilt Rewards Australia allows product upgrades within the Bilt card family. You can request an upgrade through the Bilt app, and the process typically takes five to seven business days. Your existing points balance is preserved, and your account number may or may not change depending on the card issuer’s backend system. There is no hard credit enquiry for a product upgrade within the same issuer programme.
Q: Does the Obsidian’s 50,000-point rent cap apply per calendar year or per membership year? A: The 50,000-point cap applies per calendar year — 1 January to 31 December. If you start using the Obsidian in July, you have slightly less time to reach the cap within the year, but the elevated 1.5x rate means you need only AUD 33,333 of remaining annual rent to max out, which is achievable for most renters within six months.
Q: Are there any Australian mid-tier cards that earn better than the Obsidian on non-rent categories? A: The AmEx Platinum Edge earns 3 Membership Rewards points per dollar at supermarkets and 2 MR points per dollar on fuel, which at a 1:1 transfer to KrisFlyer equals 3 and 2 miles per dollar respectively — competitive with the Obsidian’s 4 Bilt Points on dining and 3 on travel. However, AmEx MR transfers to Qantas and Velocity at a 2:1 ratio, halving the effective rate for those programmes. The Obsidian’s 1:1 transfer to Qantas and Velocity makes it the stronger mid-tier earner for those specific programmes.
Q: Is the Obsidian eligible for Bilt Dining bonus points? A: Yes. The Bilt Dining programme, which offers 5x or 10x bonus points at partner restaurants in Sydney and Melbourne, is available to all Bilt cardholders regardless of which Bilt card they hold. When you pay with the Obsidian at a Bilt Dining restaurant offering 10x, you earn 4x from the Obsidian’s standard dining rate plus 6x from the Bilt Dining bonus, for a total of 10x. The bonus caps and partner restaurant list are the same across all Bilt cards.
