Mogg continued his brilliant start to the season by helping lift the Brumbies to a 30-13 triumph over the Melbourne Rebels at AAMI Park on Friday night.

He scored the opening try and set the platform for Clyde Rathbone to score his first five-pointer in five years.

But less than 24 hours before taking on the Rebels, an ill Mogg was on limited duties as he battled a short-term gastro bug.

It didn't affect his performance, however, and while Deans was in the crowd, Mogg said his focus was on being consistent for the Brumbies.

''I had some good games and some bad games last year, now my goal is to just play 16 games for the Brumbies at fullback and get that consistency. If I'm playing well, I might get a chance, but my goal is on Super Rugby,'' he said.

In the first two weeks of the season, Mogg has shown his blistering pace to run past Wallabies Digby Ioane and James O'Connor to score two of his tries.

The 23-year-old credits Brumbies athletic performance director Dean Benton for his ability to now run a blistering 10.6 metres per second.

Mogg has also added 11 kilograms to his frame in the past three years and coach Jake White believes Mogg has something special.

''I think one thing about Jesse, he's got something there that other players don't have. He's really quick, he's got a great left boot,'' White said.

''I think the more he appreciates how quick he is and the more he understands how good he is when he has a foot race, the better he's going to become.''
