The GG The One is not available right now because of problems with the fabric (spinnaker)
The Luxe tents do have an Aussie agent with retail outlets as well as internet sales:
http://www.backpackinglight.com.au/The Habitat is similar to the Hubba Hubba, just under 2 kg, the Lightwave is a bit like the TN Laser with vents, 1.385kg on my scale(packs small)
The TT Rainshadow is very large for 1-2 people but you could look at the Double Rainbow at around 1.1kg .
This stands up nicely without any guyropes although in strong winds it can use some.
If you are not in a hurry and use trekking poles you may want to take a look at the new TT StratoSpire 1 or 2.
The one , a bit like the Scarp 1 , can take two mats in emergency or for a close couple (a man and his dog...)
