As the others have stated, uniforms, accomadation, lineage, meals, drinks, etc, but you will get a break down of the costs, from the Teams managers. When I first made a WDV team, it was mandatory at the first week end of trials, for all attendees to take a raffle book home and sell the book of 50 tickets @ $2 a ticket, (for a chance to win a digital camera in 2002, and a palm held computer with blue tooth in 2003) this enabled bowlers to broaden their area and chances of selling, to MORE ppl than just bowlers, and it was not just "yet another" chocolate drive. When you made the team, the tickets that you sold, then came directly off of your costs, hence the more tickets you sold, the less you had to pay. I found that out the 2nd year, and was able to pay for all my costs, less the airfare, so I was able to raise over $700 towards the $1500 involved in going to Townsville in 2003. In 2002 as well, we had just amongst the actual WDV team, that we all donated a prize, and we had a huge raffle that was drawn at the uniform presentation night, with door prizes as well, so in 2002, we had EVERYTHING paid for, AND got a refund. We took a cruise trip as a team, around Syney Harbour, all paid for, and all our meals outside of the actual WDV were covered as well. So, if the team gets their heads together, and organizes, it can be very inexpensive. The reason that costs vary as well, depends on the state, where they are travelling from and to, what accomadation costs are for the area, etc.
