Daniel Ricciardo's three-place grid penalty was still weighing on his mind after qualifying at the Australian Grand Prix.
The home favourite was penalised on Friday for speeding under red-flag conditions, meaning his P5 at the end of Q3 on Saturday was only good enough to see him start from P8 in Sunday's race.
“I thought [the grid penalty] was unjust," Ricciardo told Sky Sports F1.
"A penalty sure, there are reprimands, fines, other things but to shoot me in the ankle before the season has started – I thought they could have done better.
“From fifth we go to eighth. The first parts of qualifying were OK but at the end we missed a few tenths. It looked like it was all in the first sector.
“I don’t really know with the balance what more I could have done there. For sure it was frustrating a little bit.
“We’re starting on the supersofts and hopefully that works to our favour and later in the race we can make some things happen.”
