"It would be the biggest thing I struggle with," said Venus. "You try to make do but it is not easy. A coach can pick up so many things, they notice things that you don't and can give you feedback straight away. It also stops bad habits creeping in."
In New Zealand, Venus works with former Davis Cup representative William Ward, who also accompanies him to some grand slam events.
"Within a few weeks back here things start to click," said Venus. "You definitely improve and I feel as ready as I can be."
Venus enjoyed a good 2015 season, with a first ATP doubles title (Nice) and two other finals, some memorable Davis Cup matches and that night last January, when he saved three match points in a 5-7, 6-3, 7-6 (9-7) win over Alejandro Gonzalez.
"When I think about the atmosphere last year, it still brings a smile," said Venus.
Venus, who gained his wildcard after winning the national championships, has had a different build up to last year. He played an invitational tournament in Te Anau and then doubles in Brisbane.
Paire is the most difficult opponent Venus could have drawn, the highest ranked player outside the four top seeds, who receive a first round bye.
Venus' match caps an impressive schedule today, with former winner Philipp Kohlschreiber, 2009 finalist Sam Querrey, sixth seeded Italian Fabio Fognini and defending champion Jiri Vesely also in action.
American Jack Sock was the most impressive performer yesterday, blasting world No56 Victor Estrella Burgos off the court 6-0, 6-4 in 49 minutes. Burgos ain't no mug -- he is the first player from the Dominican Republic to make the top 100 -- but couldn't get anything going against the world No26.
Australian qualifier Matthew Barton (world No299) achieved a remarkable 6-3, 3-6, 6-3 win over Steve Johnson (No30) in his first match at ATP level.
Dutchman Robin Haase and Thiemo de Bakker also progressed.
