I have had access but have needed to be creative about it. I gained access by searching otca in google then clicking the ozformers link.

The following didn't work:
-clicking on the remembered address suggestions from the drop down menu of the address bar in internet explorer
-typing in the front page address www.otca.com.au in the address bar
-trying my android phones browser
-using safari on my iPad and a friend's iPhone

Just tried using google chrome as a browser and that worked fine.

Not sure what any of this means but I hope it helps.
