I have a double rainbow and think the interior feels very similar. I was suprised at the amount of room when sitting up ( I'm 6ft) Definitely has more usable room than the Contrail. The floor would be my only concern in Oz, if it gets too many holes I will replace it with silnylon or something. It pitches really tight, had it out the other night when a front came through,gusty winds all night, held up no problems. I am always suprised when these light shelters hold up to so much abuse!
