Brisbane QLD, Australia, 4 January 2016 | AAP

Adopted Australian Ajla Tomljanovic has suffered an opening-round defeat to Spain’s Carla Suarez Navarro at the Brisbane International.

The Spanish sixth seed took just over an hour to claim a 6-1 6-2 victory over Tomljanovic at Pat Rafter Arena.

Suarez Navarro, the world No.13, will face Sam Stosur in the second round after the Australian beat Slovakian qualifier Jana Cepelova later on Monday.

Following the match, Tomljanovic revealed she had torn an abdominal muscle in practice last week and had been hampered by the injury throughout.

The world No.65 has been granted a wildcard for next week’s Apia International Sydney but says her focus is on making sure she is fully fit for this month’s Australian Open.

“My plan was to go to Sydney. That might not happen,” she said.

“I still don’t know. Have to see how it pulls up in the next couple of days. If Sydney is a no-go, that doesn’t matter as long as I’m ready for Melbourne.”

Monday also brought an exit for Brisbane teenager Priscilla Hon, with the 17-year-old beaten 6-4 6-4 by American qualifier Samantha Crawford.

Crawford next meets the winner of the match between Swiss seventh seed Belinda Bencic and Italian Sara Errani.

Tomljanovic and Hon’s exits mean Stosur is the only Australian left in the women’s draw.

Later on Monday, Aussie wildcards Ben Mitchell and John-Patrick Smith were also eliminated from the tournament.

Mitchell fell 6-2 6-4 to German qualifier Tobias Kamke, while Smith began strongly before fading to a 4-6 6-3 6-2 loss to Denis Kudla of the United States.
