Hidradenitis suppurativa,burns,head injury, severe arthritis

My parents have been together for 28 yrs,and I'm so over watching the systems fail them with their years of injuries and health problems.

My dad had severe electrical burns after he cut through a 11,000 volts power cable (which was failed to be located)in 2008.He now lives with a head injury work related in 2014(which means they lost their house)and then he was hit by a random person with addiction issues and struggles even more so with basic everyday tasks and now live in a caravan full time,he has had 2 full hip replacements,has now found out his arthritis is crumbling his spine and now on a stick,and this condition will only decline.he was told that his burns will affect him later in life(which they are now in a really bad way).My mum lives with a very rare condition that has no treatment/cure called hidradenitis supportive as well as CRPS, fibro, PTSD they both basically look after each other as have no family support and I live close by to help them with health issues as best as I can.I have started this page as their hot water cylinder has died and the caravan they live in is needing quite a lot of work to get it wheel chair ready ,there non funded health issues my mum dressings are between $10-$20 per day I totally get that there is the working poor but with there weekly acc payment it was enough to loose their home and just enough paid to NOT be entitled for css or Winz help .I'm hoping to raise as much as possible as they always done for other people,please help them
