General manager Scott Sinclair said the Bend's high-grip surface and low tyre degradation on Supercars' rarely-used harder compound rubber meant it was not entirely representative.
"This track is pretty unique, the surface, obviously the hard tyre on a high-grip surface is a different combination to what we’re used to, and the nature of the circuit is different to a lot of other tracks," he told Supercars.com.
"We’re not reading too much into it, but at the same time it’s another track we’ve been able to come to and qualify in the top-five, so basically since Phillip Island we’ve been in the top five at every event.
"We’ve proven we’ve got good one-lap speed and need to work on our race execution."
Caruso qualified third on Saturday – sharing the second row with Kelly – and fifth on Sunday, when he finished ninth on an aggressive strategy that didn't pay off.
