Doc Robertson wants more Wallabies action

Waratahs prop Tom Robertson has vowed to put rugby before his medical studies as he attempts to forge a long Wallabies career.

Robertson made his Test debut off the bench in last week's 36-20 Rugby Championship win over Argentina in Perth.

The 22-year-old passed his physical test with flying colours, but he faces a difficult theory test on Wednesday when he fronts up for a big medical exam.

Robertson is studying to become a doctor, and so far he's been able to juggle his medical degree with professional rugby.

But that's set to become more difficult as Robertson progresses on the international stage.

Becoming a doctor is a huge passion for Robertson.

But nothing beats representing the Wallabies.

"The Wallabies come before anything," Robertson said.

"Uni's been very supportive and I'm sure they will be in the future. But you don't give up a Test cap for the Wallabies for anything.

"The Wallabies will come first no matter what."

Robertson has been studying hard for his upcoming exam; observed structured clinical examination on respiratory and muscular-skeletal sciences.

In layman's terms?

"It's a test on lungs and muscles on patients," Robertson said with a smile.

"I've got to pass it in order to pass the year. It's a big test, but (making my Test debut) was probably a bigger one.

"They stole the ball on my first ruck, which was not a great introduction.

"But hopefully I made up for that. We got a couple of tries while I was on."

With the All Blacks having already won the Rugby Championship, the race is on to secure second spot.

The Wallabies (nine points) currently occupy that position, but South Africa (six) and Argentina (five) are still within striking distance with two rounds still to play.

Australia face off against South Africa in Pretoria on October 1, before taking on Argentina in Twickenham.

Robertson, who was called up against Argentina last week after Allan Alaalatoa injured his knee, is desperate to get another shot.

"You don't want to just get the taste for one Test. You want it every week," Robertson said.
