Now that the Tri Series is on for the next 3 years, RL authorities should make the most of it. It could incorporate the test series we have come to know about i.e. the Trans Tasman Series (Kangaroos Kiwis), the Ashes (Kangaroos Lions) and the Baskiville Cup (Kiwis Lions).
I would stage it like this if 2004.
APRIL - ANZAC Day test between Kangaroos and Kiwis in Sydney. 1st game to count towards Tri Series.
OCTOBER
* 3rd - NRL GF.
TRI SERIES CONTINUES
* 8th-10th. Trans Tasman Test 2 (Australia). England SL Semis
* 15th-17th. Trans Tasman Test 3 (NZ). England SL GF.
* 22nd-24th. Ashes Test 1 UK
* 29th-31st. Ashes Test 2 UK
NOVEMBER
* 5th-7th Ashes test 3 UK
* 12th-14th. Baskiville Cup Test 1
* 19th-21st. Baskiville Cup Test 2
* 26th-28th. Baskiville Cup Test 3.
The Tri Series would thus be made up of 9 tests rather than 4 as is probably the plan, but it would give a feast of footy to all three countries. So either the team with the most wins at the end of the round robin would win the Tri Series.
