flat Roof Shed Bracing

Hi guys,
i bought a second hand 6x3m flat roof/skillion shed and i am just about done framing it up. The roof has about 150mm fall over 3m. The open end wall has a single panel garage door to go in, hence the big opening. When I push on the long side walls there is still a bit of movement in the structure. I am worried once i get the wall cladding on the framing it will not handle the wind loading. I am in Sydney metro.
This is the cladding i am using http://www.renovateforum.com/f224/wh...adding-107019/

Is there any other bracing i can/should do. I am thinking something between the roof rafters and the walls. Most of the fixings and tie downs i have followed AS1684.

any advice would be greatly appreciated.
