The all-conquering Queensland side have set their sights on regional success after wrapping up a third A-League crown in four years
He posed with the Courier Mail newspaper that trumpeted the club's success – but Mulvey isn't resting on his laurels.
"Thomas [Broich] said to me last night, 'Gaffer I think I've won everything now that there is to win in Australia'. In his own modest way.
"And I said, 'Tommy, have you won an Asian Champions League medal?'
"And he replied, 'Oh, good point'.
"So there you go, there's the next challenge."
Mulvey added that the goal is to be the number one club in Australia and Asia.
And Mulvey issued a clarion call to Brisbane and Queensland fans for next season.
"We made great strides this year. Bringing the average up to around 15,000 per game. Next season I'd like to see us average 20-25,000.
"Because if that's not a night's entertainment, I don’t know what is."
The enormity of Roar's achievement is only just sinking in for Mulvey, who remained a relaxed figure at today's press call.
Though it was emotional 16 hours earlier.
"I managed to hold it together on the field for the majority of time after the game - till my daughter came onto the pitch," he said.
"And that was a special moment with her."
Mulvey added that star striker Besart Berish was leaving with the love of all at the club and dismissed suggestions of a frosty reception when the Roar hero returns in the blue of Melbourne Victory.
Mulvey also dismissed comments from Wanderers keeper Ante Covic that referee Peter Green – being a Queenslander – should not have refereed a game featuring a Queensland club.
"I think that's an inappropriate comment because I think the referee handled himself very well," said Mulvey.
But after a game which was viewed by around 700,000 on TV and live – plus a global audience estimated at 250 million in around 57 countries plus streaming globally – Mulvey was proud of the league.
"We've come of age, haven't we," he said of the A-League.
"And we've got so much to look forward to. The World Cup, Asian Cup so with all those things, I think we did the game proud and the A-League proud last night."
There will be a tickertape parade in Brisbane on Tuesday to give Roar fans a chance to celebrate winning a third championship.
