The biggest online celebrity in Australia is a 22 year old lady called Natalie Tran.

Tran’s YouTube channel is the most subscribed in Australia,[3], as well as being widely watched internationally, with more than 200,000 subscribers[1] and over 79 million views in total.[4] This popularity has led to media coverage in the Sydney Morning Herald,[5][3] Western Australia Today,[6] B&T Magazine (March 2009), Báo Viêt Luận Online,[7] Việt Tribune,[8] VnExpress [9] and Triple J radio.[10]

Think about those numbers for a while. Tran probably has an audience bigger than many Australian broadsheet columnists and in excess of some US pundits.
