you can do it but dont be expecting a great luxurious life style! we had simular and my husband is a plumber and we have 4 kids to! i will say finding work for your husband not a problem so easy lots of work for plumbers but the big but he will need to go to tafe regency road plumbing school to do a short course to get a licence. this will allow him to work for someone then if in the future you want to work for himself will need to do a 2 year 10 module course to get that licence. also shop around when looking for work companies vary loads from $20 an hour to $40!!!! we have a house that we brought so have spent money there but have to say its all gone lol you will more than likely be entiltted to family tax benifit and if you dont work you will get both a and b so that will boast your income!!!
