I picked up this post from AustralianSpeedway.com:

Press Release
10th January 2008
To the Speedway World please keep former Aussie Track Announcer
Outback Andy [Andrew Foster] in your prayers as last week he had a
heart attack landing him in hospital for 3 days, and further tests
show he has a mass on his left lung,tests in the next 2 weeks will
give us a better idea if it is cancer or not.

Anyone knowing Andrew would know having him in hospital is equal to
putting a lion in a cage,He could not wait to get home and start
planning for the 2008 season at Altamont Motor Sports Park Tracy
California as a Track Announcer for the 5th year.

The good news is Andy and Robbyn have just purchased a new 34ft
motorhome which will serve as a mobile office on race days and a place
for Robbyn to hang out during the long days at the race track.Our next
road trip planned subject to Andys health will be a round of the World
Of Outlaws at Tulare in late Febuary.Once again please keep Outback
Andy in your prayers.

Robbyn and Andrew Foster.
