As suggested, Victoria will hold the series in December next season, with Alexandra Park the following year and Menangle in 2020.
That cycle will then repeat with Addington taking the New Zealand-based slot in 2022 while it is expected it will return to Alexandra Park in 2025, although that is an awfully long way away just yet.
While it was already known the series was coming back to Alexandra Park, its return to Addington will be warmly received as the track is still the spiritual home of harness racing in Australasia.
The series is likely to be two rounds of heats a week apart with the initial A$500,000 final a week later in mid-December.
The New Zealand-based series can only help both the New Zealand Cup carnival, which will run directly before the series and the Auckland Cup, which will be about two weeks after it.
Not only should it ensure more Australian horses cross the Tasman it means the Kiwis who head to Victoria or New South Wales for the Inters will have shorter flights to get there or travel home for the Auckland Cup and the series won't be as taxing.
Racing traditionalists will also be hoping the change of venues will prompt serious discussion over the return to the trotting series, which was scrapped for no good reason five years ago.
On the subject of trotters the best one still in work in Australasia makes his long-awaited public return on Saturday when Speeding Spur heads to the workouts.
The age group and Great Southern Star hero has had an enormously interrupted career over the last 16 months but has thrilled trainers John and Josh Dickie with his soundness this campaign.
If he holds together he will return to racing at Alexandra Park next month at a time when the elite trotting ranks are shorn of his arch rival Monbet and there is no dominant force.
