No wins, no worries for Bernard Tomic.

The beanpole Australian enters his ninth Melbourne Park campaign with perhaps his worst on-court preparation – and with clouds over his fitness – but he’s not about to let it get him down.

Perhaps that’s because in eight Opens, Tomic has an impressive 15-8 winning record, with a sole first-round exit to then-world No.1 Rafael Nadal in 2014.

Tomic has reached the fourth round of his home slam three times in the last five years; making him Australia’s most consistent performer this decade.

Or perhaps Tomic is confident because he doesn’t read anything into local lead-up tournaments.

“I don’t really rate these matches as winning or losing, Sydney and Kooyong,” he said on Saturday.

“That’s not important to me. What’s important for me is to get out on the court, do my thing and work on a few things I needed to do and just to be ready mentally for the Open.

“I played very good in my past here where I haven’t been prepared for tournaments. Sometimes it happens just like that.”

Tomic lost his first round at the Brisbane International to former world No.3 David Ferrer, winning an exhibition match over Dominic Thiem but losing twice at Kooyong this week.

The 24-year-old made waves with the revelation this week that he had shed 4.5kg in quick time in an effort to be fit for the year’s first major.

But when asked if his weight had stabilised, he responded sharply, saying “I’m not going to answer that”.

Tomic will play on Monday against Thomaz Bellucci, a left-handed Brazilian who he rates as a “top-10 player on clay”.

“It’s going to be a tough match. He’s not easy to play for me, so I have to get ready for this match with all my effort,” he said.

“He’s very intense. He’s beaten a lot of top players. I think he’s reached almost top 20 in the world, won multiple titles.

“I have to come into this match 100 per cent from the first point.”

Tomic hopes a partisan local crowd – perhaps on Hisense Arena – can help fire him towards the second week.

“I’ve got to use the moment, use the crowd,” he said.

“Obviously the fans get behind me, I’m sure they will. They always get behind our Australian players and support them to their limits. I think that’s what makes us play really good in Australia.”
