Vango Beta 450 4 person tent & a $25 item (e.g. torch). Free shipping $252.40
Found some in the big camping stores that looked reasonable (Coleman Traveller 3CV $179-ish looked ok, but small vestibule). Then I found this one in various places in the mid to high $200's (plus shipping). It gets good reviews.
There are two models around - the more recent one has the 'porch' floor built in (bath tub style). On the older ones (typically on ebay) it's a seperate sheet. You may find that one cheaper (though I don't think so).
Amberjack have 10% off with the code D7OUTFIT (not sure when that expires) and a deal that to get free shipping you need to spend over $250. The tent is $250, but the 10% off takes it under the free ship limit so you need to add something at least $24-5 to get up over $250 and get the free shipping. I selected a Fenix torch. Their site is a bit slow. They're in Narooma, NSW.
