I've been thinking of one of these [color=" #0070c0"][color=" #0070c0"]PORTABLE OXYGEN CONCENTRATOR[/color][/color] at ~$400-500 landed, your square after about 2 years rent.Apparently they provide HEPA filtered sterile O2 enriched air at up to 60kPa, bit more compact than a 35Kg 1.7 meter tall Oxy bottle.Anyone out there with any technical knowledge about this type of equipment.

For those still searching for these (like me), Williams Brewing look like they have them in stock. I have not asked if they will ship to Australia yet, I want to make sure my local stores can order the O2 bottles first!
