The few Victorians I know are AFL mad supporters but according some numbers in social media, Melbourne Storm is a successful business plan over there.
They currently has +300k followers in IG, more followers than traditional AFL teams like Collingwood or Carlton.
Just to put it in perspective. According IG followers:
Storm 325k
Collingwood 298k
Carlton 241k
Rebels 58k
With this I don't say that Storm is the most popular sport team there but they have grown consistenly in the last years with good performances and winner teams. Imagine how good would be the Rebels if they have 200k followers. I mean, there's no an Aussie Super Rugby team who has 200k followers there. The most popular is Brumbies with 121k
