Well were happy you've joined us.

We're still growing so please be patient. Other will respond.

It will be a little harder for me to give an opinion on what would be best in your area as I know the market is much different in Australia.
Angus are great cattle. What cattle are around your area? Are they angus?
Do you have a local auction yard? That would be a great place to start if you do. See what cattle go for what $. Around here black hided cattle are king. Is it that way there? See what size sells best. This will help you decide what the best market for your area will be. Go more than once though. Prices/demand change throughout the year/seasons. Talk to others there. I'd bet (as is here) there would be people who would be willing to give opinions on what would be best for your area/situation.
Are you interested in having bulls and raising calves? There's a lot of work involved with this. In my opinion it's worth it but you may want to do something else like purchase and raise feeders or something.
What kind of market are you thinking? Private sales or loads of cattle to the local auction?
