The hazardous smoke haze blanketing the country and its capital has sent the Australian Baseball League into uncharted territory, with officials introducing new legislation to combat extreme conditions.

League officials will use an air quality index of 300 as the threshold to cancel matches and the new rule has already come into play as fires rage across south-eastern NSW.

The four-game series between the Canberra Cavalry and the Adelaide Giants was cancelled on Wednesday, little more than two weeks after smoke haze forced a match at Narrabundah Park to be abandoned.

Cavalry director Dan Amodio has backed the new policy and says it removes subjectivity from the decision to cancel or continue play.

"In any situation like this, it's really great to have an objective standard to follow," Amodio said.

"It takes all the subjectivity out of it and keeps everyone on the same path.

"During our Christmas series, there was no rule in place in the ABL about when to stop playing according to hazardous air quality. We had our game suspended because it just felt really bad.

"Out of that weekend, the league created a rule which is in line with most other professional sports.

"It definitely played a factor looking at the weather reports, the chances of getting in any games [this week] according to those new rules was very unlikely."

The air quality rating peaked at 5185 on Wednesday night at the Monash air quality station, forcing the Cavalry to cancel training on New Year's Eve.

The Adelaide series was due to start Thursday, but the club and league officials were forced to abandon the series as Canberra's air quality continues to deteriorate.

The clubs will split the series and earn two wins each if the matches cannot be rescheduled.

The ABL will make a decision in the coming days but Amodio says it's unlikely the series will be played with only three rounds remaining in the regular season.

Purchased tickets are redeemable for the Cavalry's final home series against Auckland Tuatara in two weeks.

All ticketing revenue from the Adelaide series will be donated the NSW Rural Fire Service and the Cavalry will host a 'livestream-a-thon' to raise further funds on Friday.

"We're encouraging people to keep buying tickets because all the money raised from ticket sales this week will go straight to the RFS," Amodio said.

"All tickets that were purchased for this series will be redeemable for our next series against Auckland."

The Cavalry sit second on the north-eastern ladder with 11 wins and 13 losses, after notching six wins in their past two series.

"The team has really been on a roll, they've won a handful games in the last couple of series and have been playing well," Amodio said.

"From a momentum standpoint it's tough but Keith [Ward] and the players are professionals who have been through stuff like this before.

"I'm sure they'll be testing the indoor facilities and seeing how much work they can get in. What they've been working on now, it's just putting the pieces back together and trying to make something work for next week."
