Tamworth or Dubbo are great holiday places love the Dubbo Zoo

paradise resort in Queensland. West beach caravan park in Adelaide,

coffs harbour, the gold coast, sunshine coast. it is the accommodation that bumps up the cost

Anywhere in Tassie. Fresh air, stunning views, friendliest people in Australia, lots of family activities and your keeping your money in Australia, boosting the local economy

I think it’s really hard to answer this – it depends so much on your own family and the sorts of things you like to do. I recently put together some questions to help parents think about the sort of accommodation that might suit them. It might help you http://www.familyfriendlyaccommodation.com.au/what_makes_it_family_friendly?

most of the big 4 holiday parks are good – affordable and usually have lots of activities for the kids

Reading the other answers you have, there seems to be a common theme of camping or cabins in a caravan park. Its great to hear so many families enjoy exploring Australia. We invested in a Camp 7 book and HEMA GPS. Our school holidays are spent exploring little, out of the way places, away from the crowds and traffic. The kids take a book each, a drawing/colouring book, ball, and one or two other small games to share. The rest of their fun is whatever we stumble across, be it a bush walk, a local museum, a park, or something quite unexpected. In QLD, we find the coast very busy, so mostly stay inland. Sometimes we pick a town and try every free campsite in that vicinity (Thankyou Camp 7!), only covering an hour or two every few days. Other times it’s a massive road trip (QLD-NSW-ACT-VIC-SA-and Return was our biggest so far). Our expenses are mostly food, which you’d have to eat at home anyway, fuel (so budget dictating a short drive or a longer one), and a few dollars here and there on treats. Outback towns often have accommodation for caravans & camping at the showgrounds cheap too, often much cheaper than caravan parks and still with hot showers and other facilities. One of my favourites, MEANDARRA QLD $10/night per van, not per person, with power, water, hot showers, flushing toilets, and right on the creek if the kids (or hubby) love fishing. Run by the council. If you visit, don’t miss the Meandarra ANZAC museum. They’ve built the building around the aircraft, then moved the tanks and other vehicles in before finishing it off. Have fun!

Caravan Park at West Beach in Adelaide. Think it is called West Shores? Close to the city, close to Glenelg, great facilities.

A small town beach holiday could be a winner. Beach time, maybe fishing, kids can go buy self an ice cream at local store.
Yamba, Lake Cathie, Hat head …
Caravan parks are good, cos often other kids to play with, or kid play areas/events.

We have taken to going to farm stays. Heading off to our 4th one in December. All the walking and feeding animals and just being in the country is great. Apart from food that you you bring from home, all the entertainment is outside the cabin door. They can seem a bit expensive at first, but with no extra expenses possible, they work out relatively affordable in the end.

Depends on what you’re looking for and your budget. As Mom90758 said, Fiji is a marvellous place to take the children – they are looked after really well with children’s clubs, swimming comps. and evening fun nights. We stayed at Naviti which is all inclusive – food, accommodation and some tours at no extra cost and the children are really looked after well.
Here in Aust. we found that the 4 star caravan parks have lots of children activities and they are not really that expensive whether you have your own van and hire the site or hire one of their vans on the site. My children loved being in both places.

Anywhere your child has you to watch over them and keep them safe and amused is a great holiday. Just a day trip to the park or beach would be loved

We love the Caloundra Waterfront Holiday park. We book a cabin. Considering we have 4 kids, going on Holiday is often very expensive but we find it reasonably priced.

Are you planning to go camping, caravaning, cabin in a caravan park, motel, or equiped flat?
It also depends how old your children are and what state you wish to travel in.
In SA – Port Vincent, Moonta, Wallaroo ,Stansbury on Yorke Peninsula; Kangaroo Island,
Port Lincoln, Whyalla, Cowell, on Eyre Peninsula; Victor H

In SA On Yorke Peninsula – Port Vincent (very popular), Moonta, Wallaroo, Stenhouse Bay, Stansbury, Edithburgh. Eyre Peninsula – Port Lincoln, Cowell, Streaky Bay.
Aldinga, Victor Harbor,(there is a horse and cart ride from the coast in the town over to Granite Island where you may find a colony of penguins but please do not touch them. They swim back onto the island at night after catching and eating fish during the day. Port Elliott, Goolwa (where the Murray River goes to the sea), Encounter Bay. In the Barossa Valley (wine production area) at Williamstown is the Barossa Reservoir which is also knownthe Whispering Wall. There is two places one on each end which you can lean against the wall ( it is fenced) and talk to each other. The kids love it. The only other one known in the world is in Sweden. In Tanunda there is an old steam train (not working) at a park next to one of the Wineries. In the Lower South East near Mount Gambier is the Blue Lake, Sometimes the water is bright blue in colour. There is also a garden in a crater but that probably won’t interest the children. In the Flinders Rangers there is a lot of pretty gorges, Wilpena Pound (there is a great motel and camping ground there – it has won travel awards. In the Flinders Ranges the colour of the rocks and mountains change colour during the day. A lot of artists spend months up there.
In Quorn there are some old and some new great motels and a caravan park. There is also steam train rides at weekends run by volunteers. They use other trains during the bushfire season. Part of it travels near the road Some kids watch for the cars especially at the bridges on the road.

Caravan places near the beach or river so you can have cheap accommodation as well as somewhere to swim.

Farm stays are a good cheap option too and the kids will love the animals and the experience.

qld gold coast theme parks, use vouchers

Camping is always a cheap and cheerful option for a family and Australia has some incredible destinations. Camping in some resorts/parks is a good idea too as you have a pool and activities and facilities.

If you mean domestic camping is always lots of fun, we used to do it all the time when I was little and we’ve started the same tradition with my daughter.
If you want something a bit more Tasmania is a great place to visit, you can hire camper vans and drive around to all sorts of place, it’s an amazing place. I’d say the same with New Zealand as well.

I would recommend you the Fiji Islands. A beautiful place, great for adults and kids.
