Test matches will be played at the WACA Ground for the foreseeable future after Cricket Australia rejected suggestions that Canberra would replace Perth as a primary international venue.
But CA, the WACA and the State Government recognised that a big cash injection was needed to improve the ground's ageing and decrepit facilities.
As the WACA's proposed $500 million ground redevelopment collapsed, reports emerged that Manuka Oval in Canberra would replace Perth as a likely alternative Test venue.
This was quickly rejected by CA chief executive James Sutherland who said each mainland State capital would continue to be allocated an annual Test match.
"Although Perth won't host Test cricket next summer due to a shortened international season, we are committed to playing Tests in every State capital ," Mr Sutherland said.
The third Test was an ordeal for many spectators with searing temperatures, absence of shade, difficulty in getting refreshments and aggressive security staff sapping the experience of watching Australia's victory.
WACA chairman Sam Gannon said the ground had to be improved but he was confident that Test cricket would not be at risk, if the shade could be vastly improved.
The WACA is interested in playing blockbuster matches at the new Burswood stadium but is not convinced that Test matches would be a success in a 60,000- seat venue.
"We have had Tests allocated until 2020," Mr Gannon said.
"But unless we can get government assistance or a future board gets a development going that would generate enough cash to improve the facility, it is undeniable that we have too many patrons sitting in the sun."
Sports Minister Terry Waldron was confident that the WACA Ground would continue to host Test cricket.
Mr Gannon said the WACA was committed to playing a one-day international and Big Bash matches at Burswood in 2018 but was unsure whether Test matches would attract enough spectators to make it viable.
The biggest Test crowd in WA was 24,268 at the first day of the Ashes Test in 2006-07. There have been only eight other crowds of about 20,000 in the past decade.
