Hey Sam,
Don't know about sourcing financial reports but it's not surprising they only have balance sheets up to June 2008 - most listed companies are only required to produce yearly reports (some have to or choose to also produce interim reports).
As a result, the latest available report (balance sheet) is the June 2008 one. The next set of reports produced will be for 1 July 2008 through 30 June 2009. It also takes a substantial amount of time for the company to compile it's data and to produce the reports - from memory they have about 3 months to do so. This seems to be one of the problems with fundamental analysis - the timeliness of financial data - a lot can change in 3 months.
There should be some info on the ASX site regarding the reporting requirements for listed companies; a search there might give you a better understanding of what you can get, where you can get it and when.
Cheers,
AMSH
