The Thunder's top five bid has received a huge boost with officials confirming their clash with the lowly Melbourne Renegades will go ahead at Manuka Oval on Wednesday night.

Concerns hovered over the fixture amid fears it would have to be moved due to Canberra's hazardous air quality in recent weeks.

But conditions have cleared with the Thunder hoping they can escape the fate which saw their last outing at Manuka Oval abandoned early in the run chase due to a thick blanket of smoke in the city.

The prospect of losing another game would have been a major blow for the fifth-placed Thunder, with two points separating third from seventh.

Sydney have a golden opportunity to find some breathing space when they meet the Hobart Hurricanes on Saturday, before meeting the struggling Renegades in Canberra next week.

"We know how tough the competition is and how tight it is," Ferguson said.

"Very rarely do you see a big gap between any of the teams throughout the table, so we know we're in a dogfight for finals spots.

"We're really excited about the games we've got to come. Obviously you don't want to get too far ahead of yourself and only focus on the game you've got coming up, and the Hurricanes will be a tough one.

"The past few games haven't gone the way we would have liked but we're still confident in the group we've got and the side we've got.

"We've played some really good cricket in this tournament so far and our best is yet to come.

"This game will be a tough one against the Hurricanes, no doubt, Matty Wade is in really good touch and Scott Boland is bowling well.

"They'll throw some challenges at us but we're really excited and pretty confident going into this next one."

The smoke haze which threw Canberra's last taste of Big Bash cricket into disarray was a by-product of the NSW bushfires.

Relief appeals have garnered millions of dollars from A-listers around Australia and abroad as fire-stricken communities continue their battle.

Cricket legend Shane Warne's baggy green cap was purchased in an auction by the Commonwealth Bank for $1,007,500 amid plans to take it on a tour to raise money for communities devastated by bushfires before being donated to the Bradman Museum.

The impact of the fires has put so much into perspective recently, just as it did for Ferguson when a smoke haze denied the Thunder a near-certain victory in Canberra.

"I don't know if 'haunting' is the right word," Ferguson said.

"But when the smoke started to come across the ground, very quickly you started to turn your attention to the fact that there is obviously a hell of a lot of damage being done around the area.

"People are losing homes and we're losing a lot of native wildlife. It was quite a tough experience for everyone involved.

"We as a country really do pull together as a team when these types of disasters hit our country. We pull together as one.

"It's great to see the amount of support the firies on the front line and the victims of the bushfires are starting to receive."
