NBL officials are bracing for further fixture disruptions after Western Australia's tough border stance forced an overhaul of the 2021-22 season schedule.
Less than a month after announcing a full fixture, the NBL on Wednesday released a re-worked schedule with only the first six rounds locked in.
Newcomers the Tasmania JackJumpers were initially set to play the Adelaide 36ers on December 3 but will instead take on the Brisbane Bullets in the season opener.
The 36ers will travel to Perth to play the Wildcats at RAC Arena on the same night.
The Wildcats are now slated to play five home games in the first three weeks of the season and could then be set for a long stint on the road amid ongoing uncertainty surrounding the WA border.
WA premier Mark McGowan will open the border after the state reaches a 90 per cent vaccination rate and has promised to reveal a target date once that figure hits 80 per cent.
The New Zealand Breakers could face an even longer period away from home and are currently scheduled to play at least eight consecutive road games in Australia to start the campaign.
NBL commissioner Jeremy Loeliger remains confident all clubs will play 14 home games this season.
"We have the ability to swap and change when necessary but will always maintain the integrity of the schedule and we will always put fans first," Loeliger said.
"Getting teams into states and fans into venues safely remains our absolute priority.
"We will maintain a flexible approach to the schedule to ensure any potential further changes are made with these two objectives at the forefront."
The NBL has an outline of what the fixture looks like beyond the opening six rounds but JackJumpers chief executive Simon Brookhouse said uncertainty over WA's border, in particular, has rival clubs expecting more changes.
"We'll just work around that and see how the Wildcats are impacted," Brookhouse said.
After the Tasmania-Brisbane and Perth-Adelaide games on opening night, round one continues with the South East Melbourne hosting the Breakers on the Saturday night.
Sunday features a triple-header, with 36ers-Illawarra Hawks, Sydney Kings-Melbourne United and Wildcats-Cairns Taipans match-ups.
The NBL season was initially set to tip-off on November 18 but was pushed back to December, with a four-team finals series now likely to begin in late April.
Meanwhile, the second-tier NBL1 competition now boasts teams from every Australian state and territory.
A Northern Territory team, to be based in Darwin, will join the NBL1 North conference in 2022 as one of two expansion clubs, along with the North Gold Coast Seahawks.
