Just came back from Mackay also on Tiger...the sporting goods allowance makes them quite a good option. They offer 1 bag of sporting goods upto 30kg for $30 each way, so i used one of the Ebonite four ball travel zip up canvas bags which weighed approx 29.5kg...then i upsized my baggage allowance for $10 each way..which allowed me 15kg of checked in luggage..that was my 2 ball tote bag....so for $40 each way i got 6 balls to and from Mackay. You get 7kg carry on so clothes went in that bag.
Hope this helps.
