TL;DR: The August peak is fading, but not far. The Brisbane metro ULP median topped out at 209.9 c/L (5–8 August), discounted about 10 cents over the next four days, and then stalled at 199.9 c/L — where it’s sat for five days now (12–16 August). That’s a shallow fall: barely 10 cents off the top, and nowhere near a real trough (Brisbane troughs have run into the 170s and low 180s). The reason it’s stalling short is the floor: the 1 August excise step lifted wholesale by ~17.6 c/L, and Brisbane’s Terminal Gate Price is still ~192.5 — so the pack at 199.9 is only about 7 cents over cost and has little room to keep dropping. The move to make while it hangs there: skip the 199.9 pack and take the independents, which are already at 185.5 — about 14 cents cheaper today.
Every cycle has a moment where the pack breaks off the peak and starts discounting, and drivers who held out get paid. This lap, the break came — and then it just… stopped. Here’s what the feed shows and what it means for your next fill.
The peak, and the half-hearted drop
Every number here is the Queensland Government price feed — what each Brisbane-metro station reported charging, carried forward to a daily median.
Ten cents off the peak in four days, then five flat days on 199.9. If you’ve been waiting for the bottom, this isn’t it — or at least, it isn’t much of one. The pack has landed on the round number and dug in.
Why it’s stalling short
The floor moved up, so the bottom can’t go as low. Wholesale — the Brisbane Terminal Gate Price — is about 192.5 c/L, still carrying the full fuel excise that stepped back in on 1 August (about 17.6 c/L once GST stacks). At 199.9 the pack is only around 7 cents over wholesale. There isn’t much discount left to give: a servo can’t chase the price into the 180s when it’s paying 192.5 for the fuel. Pre-excise, a Brisbane trough could fall into the 170s; with 17-odd cents of fixed tax now under every litre, “the bottom” is a good deal higher than it used to be. We flagged this the day the excise landed — the trough won’t fall as far as the last one, and here’s that playing out.
So what — for your next fill
- Don’t hold out for a deep trough this lap. At 199.9 the pack is already close to wholesale; the odds of it sliding much further before the next restoration are slim. Waiting for a 179.9 that may not come just means driving on fumes at the dear end.
- Take the independents now. The cheapest in the metro this morning is 185.5 — Liberty at Bellbird Park and Moorooka South, Pearl Energy Moorooka, an Ampol out at Waterford West — about 14 cents under the 199.9 pack. That’s the real saving on the table today, no waiting required.
- Watch for the next hike, not the next drop. When a shallow discount phase runs out of room, the restoration back to the peak tends to come sooner. If you’re going to do a big fill, do it at the cheap end now rather than betting the pack falls first.
The short version: the peak’s over, but the excise put a floor under how good the trough can get. Don’t wait for a bottom that’s already most of the way in — find the independent that’s 14 cents under the pack and fill there.
How we measure: Brisbane-metro stations within a box around the CBD, QLD Government price feed, regular unleaded (ULP/91), obvious data errors excluded, last-known price carried forward to a daily median. Wholesale is the published Brisbane Terminal Gate Price. “Stalled at 199.9” is five flat days (12–16 Aug) — the pack could still resume falling or turn back up; this is a read of where it sits today, not a forecast.
