WA are set to play two Sheffield Shield matches, home and away, against NSW this September in the earliest start to a domestic season in Australian cricket history.
Twenty20 franchises from both States will travel to the Champions League in India in October, requiring significant changes to the normal domestic fixtures for their parent associations.
The WACA's chief executive, Christina Matthews, was confident the WACA Ground would be ready to host a Shield match against NSW in mid-September.
"We have said we will be ready to go," she said. "And the weather in Sydney in September is usually pretty good, so there should not be a problem getting facilities up there."
The Warriors' away game is likely to be played at Bankstown Oval due to the SCG remaining the Sydney Swans home base until the end of the AFL finals.
Last season's T20 champions, Sydney Sixers, and their grand final opponents, Perth Scorchers, will take part in the lucrative Champions League after qualifying as the top two teams at the Big Bash.
The previous earliest start to a domestic season was in 1995 when Queensland hosted South Africa's Western Province in a match starting on September 26.
Cricket Australia confirmed the domestic fixtures would be finalised in the coming weeks.
CA said it was confident the player pay dispute would be resolved. CA and the Australian Cricketers' Association are poised to sign a new five-year memorandum of understanding after months of bitter differences over the size and structure of the total payment pool, the nature of revenue streams able to be captured by the players, and the number and style of central contracts.
The imminent resolution of the dispute will finally allow the States to contract and recruit players for next season.
CA chairman Wally Edwards was confident a deal would be signed by the end of the month.
"The two negotiating teams have made good progress in the past couple of days and we are all pretty confident a new MOU will be agreed before the end of the month," he said. "The board has considered a lot of the issues and there are just details left to be resolved."
ACA chief executive Paul Marsh was also confident a new deal would be struck soon.
Marsh would not discuss details of the proposed deal nor whether the ACA had abandoned a claim to a share of a potential WACA Ground redevelopment.
"I don't want to go into detail but I think the WACA would be happy with the outcome," he said. "We've made a lot of progress and while we are not there yet, and there is one more thing to discuss, we are pretty happy with the deal."
Edwards was also confident that CA would succeed with the radical overhaul of its governance structure that would see an independent board installed in October 2014.
The States will be asked to formally approve the creation of a nine-member board this August.
Each State would have one representative on the board with three independent members.
