Twenty20 cricket is set to hit Hobart with Tasmania and WA preparing for a three-hour knock before their more serious Pura Cup match at the weekend.

Wednesday's match is the third Twenty20 contest in Australia after two successful bouts in South Australia and Western Australia.

Tigers captain Dan Marsh said his side would use the match to trial five players trying to break into first-class cricket.

"It gives them an opportunity (to play with the Tigers). I think they've been knocking on the door and I think they're really suited to this style of cricket," he said.

Former Australian one-day cricketer Michael Bevan, who led the Tigers to a two-run victory over the Warriors in their ING Cup clash on Sunday, is unavailable as he has commitments with the Prime Minister's XI.

Top pacemen Damien Wright and Adam Griffith are also out of the side.

Marsh said they were hoping to score between 150 and 200 runs from their 20 overs.

"With 10 wickets in hand and 20 overs I think you can really go as hard as you like for the first six overs ... and probably expect to lose a few wickets and then in that last 14 overs, the field's going to be out so you can probably treat it like the last 14 overs of a one-day game," he said.

WA captain Justin Langer said while the 20/20 concept was not serious yet, it was a "great spectacle" that could revive the popularity of one-day cricket.

"There's been a lot of talk over the past few years that (one-day cricket) has got a bit predictable so I think guys can learn different shots and be more aggressive (in 20/20). Hopefully there'll be an overflow of positivity for the one-day game."
