Clive Rowlands managed a Lions team against a world XV at Cardiff Arms Park in 1986 to celebrate the centenary of the International Rugby Board.
Although they lost 15-7, Rowlands made history by becoming the first man to manage the side twice when he was chosen to take the Lions to Australia.
This would be the first time that Australia alone had hosted a tour since 1899.
Abrasive Scottish open-side Finlay Calder was chosen to lead the side, England's Roger Uttley named as forwards coach and Scotland's Ian McGeechan given overall control.
The structure seemed right, but the tour got off to a troubled start, Australia shining in front of the Sydney crowd in the first Test to run out 30-12 winners.
The Lions were stung and made six changes for the second Test in Brisbane.
A cheeky try from Jeremy Guscott stole the show, helping the tourists level the series with a 19-12 success.
It was set up for the decider back in Sydney where the villain of the piece would be Australia's usual hero, David Campese.
In perhaps the worst moment of his rugby career, he gifted a try to Wales' Ieuan Evans and the tourists held on for a famous 19-18 triumph.
This was the first time a Lions side had come from behind to win a Test series. But Australia had fully justified the decision to let them host a Lions tour.
The provincial games were tough and the national side would learn from the brutal campaign to go on to win the 1991 World Cup.

The tour ended with a one-off showpiece against an Anzac side, the Lions rounding off with a 19-15 win.
A British and Irish side played France in Paris later in the year to celebrate the forming of the French Republic in 1789, but several leading players were absent and it was not officially recognised as a Lions team.
