Australia isn't going anywhere, what's the harm of just giving it a shot for a year and finding out for yourself? If the social aspect is one you're concerned about, maybe factor that into your job search, since people at work are who you will interact with most (both in general, but especially when you don't know anyone else). Specifically make sure you can socialize with the team, and maybe bias yourself towards slightly larger companies since there are more people there in general to socialize with.
