Pier First is similar in fitout to the Wing First, but minus the cabanas.
However it is down a level and has limited natural light and views, is also a fair way away depending on your gate.
Cabin is a new joint Business/First offering with different food and a health bar, and the new Solus Chairs.
The Qantas First lounge is also an option.
Also the lower floor part of the Wing Business has recently reopened following renovations so it might be worth checking that out.
Most pick depending on departure gates but why not go lounge shopping.
