One entertainer is based in Mount Gambier, and it's a children's magician. That's the honest state of the list right now for South Australia's second city: after the magician, the nearest names are a duo out near the Grampians and then a run of Warrnambool cover bands and singers, all of them a couple of hours east along the Princes Highway, and the cards after those say Ballarat and Ararat. Adelaide doesn't appear at all, because it's further from the Mount than Ballarat is. So the question for anyone planning a wedding on the Limestone Coast isn't which act, it's which direction.
Victoria, mostly. The border is twenty minutes away and the Warrnambool acts play the south-west coast as their own patch, so a Mount Gambier wedding or a fiftieth is a long Saturday for them rather than a foreign trip. Ballarat has the deeper bench, with cover bands, wedding bands and a country act or two, but that's a proper drive and a bed. Book whichever you choose well ahead of the summer and Easter weekends, when the same bands are wanted at home.
Top picks are the nearby performers with the most visible reviews, then rating, then the closest; further afield the closest come first, and premium listings break remaining ties. Distances are straight-line from Mount Gambier. Ask each act whether they travel to your venue and what that costs.
Start with the from-prices on the Warrnambool bands' cards on this page, because there's no band based in the Mount to compare against, then add what each charges for the highway. A band's fee scales with heads: a three-piece with tracks and a five-piece with a horn player are different money before anyone drives anywhere. Fridays and Sundays sometimes trim the travel, since the band isn't giving up a Saturday at home.
Warrnambool ones do, regularly; the south-west coast and the Limestone Coast are one circuit for them and the border makes no difference to a gig. Ballarat bands will come for a wedding with the budget for it, and they'll want to stay the night. Put the venue and the finish time in the first message so the travel line comes back realistic.
Yes, a children's magician based in town, and for once the local act is the right one for the job. Tell them the ages and the head count, because a show for six-year-olds and a show for a mixed school crowd run differently, and say whether it's indoors; the Mount's winter is wet enough that a backyard show in July needs a plan B.
A children's magician is exactly the local act a town of families uses most: birthdays, school fetes, the Christmas party at work. For anything with a dance floor, you're reading the Victorian end of the list.
Warrnambool reads as a couple of hours and is, but Ballarat and the Grampians acts are three or more, and after a late finish nobody should be driving home through the pine plantations. Ask for travel and a room as separate lines on the quote.
Adelaide's list is deep but it's the far side of the state, and an Adelaide act will quote the full day. A tribute show or a big band might justify it; a duo for a ceremony won't, when Warrnambool has singers who'll do the drive.
