A number of Launceston Triathlon Club officials inspected the Bridport course that was also set to host the second of the state's six-race sprint series before making a decision nearly two hours before a race briefing was scheduled for competitors.

Event organiser Matthew Wheatley posted on social media early on Saturday that safety of competitors was of "the utmost importance" and the dubious conditions was "not safe to compete in".

"The way the smoke was in Launceston by lunchtime, it was way worse than that in Bridport," Wheatley told The Sunday Examiner.

Technical race director Peter Adams, who consulted Wheatley on the final call, had never seen a sight like the haze from the continuing bushfires after three decades of involvement in triathlons around the nation.

The pair enacted a Triathlon Australia policy guide relating to unsafe conditions.

"Even in the absence of that document, the practical reality at being in Bridport at 6:15 in the morning that people were getting headaches, people were genuinely feeling dizzy and visibility was down to only about 500 metres," Wheatley said.

"Putting policy to one side, there was issues from both a safety and also a health and wellbeing perspective that the question wasn't do we run the race - the question is why would we?"

Both distance races had been postponed, with organisers planning to work with Dorset council to reschedule a return date by Wednesday.

Wheatley said indemnity and insurance matters were just another contributor behind trying again on another day.

"We do, as race organisers, carry a degree of liability - we're always conscious of that. It's part of a club that has a good governance practice and putting on safe events," he said.

"Really, were we a bit gun shy? Well, we actually weren't. We were sitting back and saying there was the practical implications.

"We were sitting on the main street of Bridport and we couldn't see the water - and it's only a few hundred metres away.

"We would have had our swimmers in that water, who couldn't see the turnboy or worse, we could have lost someone in the water."

Launceston parkrun also cancelled its regular Saturday session early in the morning.

"We are being extra cautious and care about the wellbeing of you all. The air quality is worsening, so we are playing it safe," organisers posted on their Facebook page.

The day before, regulars were forewarned of a potential cancellation and posted an air quality index visual map of Tasmania that peaked at "very unhealthy" around 10am to better vindicate the decision.

But the return of turf cricket competitions continued as per normal.

This comes after Cricket Australia had suggested the SCG Test match could be halted should smoke linger heavily.

Greater Northern Raiders coach Andrew Gower said his Cricket Tasmania Premier League side had no discussions of cancelling the match or delaying the start with umpires or their opponents Clarence.

"We talked about breaks throughout the game if required - that would be relevant for anyone that had asthma or any breathing difficulties," he said.

"We took all of that into consideration.

"We ended up getting through unscathed, but the air quality was poor at times.

"It's blown away now, which is great for us for [Sunday's] game with Glenorchy.

"But it certainly wasn't a great spectacle and I think it would have been a hard day to catch out in the outfield."
