Australian singers John Farnham and Olivia Newton-John are linking up for a joint tour of their home country.

The veteran stars have lined up shows in April next year (15), 17 years after they first toured together with their Main Event concerts in 1998.

Farnham and Newton-John will perform separately before returning to the stage together for a combined set.

The trek is the latest live link-up for Farnham - earlier this year (14) he hit the road with Lionel Richie.
