While next summer's Tests against India are confirmed nothing has been resolved beyond that, with Australian officials awaiting the outcome of a report into scheduling and funding at the International Cricket Council's (ICC's) annual meeting in London next week.
Cricket Australia's public affairs manager Peter Young admitted that protecting the traditional Australian summer of cricket "is certainly one of the most difficult issues we've got."
"Looking ahead, South Africa have very clearly signalled this is a big issue for them and I don't believe we've resolved that yet. The only programme we've finalised is the programme for next summer," Young told Saturday's The Australian newspaper.
South Africa, who have their own Boxing Day and New Year's Day Tests except when they tour Australia, are seeking a review of scheduling with the ICC, reports said.
Australia are paying South Africa compensation, believed to be at least 300,000 dollars (254,000 USD) each time they sacrifice their own Boxing Day and New Year's Day Tests by touring Australia, The Australian said.
The South Africans are due to tour Australia again in the 2008-09 summer.
The newspaper said South Africa's ICC submission is supported by West Indies, who have raised concerns about funding under the current touring arrangements.
Former Australian Cricket Board and ICC chairman Malcolm Gray, who is chairing the ICC committee, said its charter has been to examine the existing scheduling through the future tours programme and to look at the funding of international cricket.
"The South African submission was along the line of concern that the existing scheduling and arrangements are equitable and the West Indian submission was based on their financial situation, putting forward that under existing arrangements it doesn't afford them sufficient financial support," Gray told The Australian.
The newspaper said it understands the committee will want Australia to maintain regular international cricket during the November to February window.
India have refused to arrive in Australia next summer until late December.
While the Boxing Day and New Year's Day Tests will be played, they become the first two matches of the four-Test series not the last two, leaving a three-week hole in December, which is considered prime time for Test cricket in Australia.
There will be no international cricket in Australia from the end of the second Test against Sri Lanka, scheduled to finish on November 20, until December 11, when Australia play New Zealand in a Twenty20 match as a lead-up to three one-day matches in the Chappell-Hadlee Trophy.
The annual one-day triangular tournament has also been pushed back, beginning in early February and running until the first week of March.
"Scheduling cricket is a bit like trying to get a Rubik's Cube aligned," Young said.
"It's really complicated and it's only getting more complicated.
"We've got a traditional season that we've been operating for a long while and we're keen to keep working with other nations to do that. The Boxing Day Test and the New Year's Test are iconic parts of the Australian summer."
Eight of the 10 Test-playing nations, including Australia, share the same cricket season.
