Casual community aged care work is always available. As a community RN my employer regularly advertise for home support workers, I'm not sure if $25 an hour is slightly optimistic though? One thing I will say is it's hard work and not a job you do for money, the aged care population need caring for correctly, I'm very passionate about ensuring our aging population get the care they deserve. If your husband is genuinely serious about it send me a PM. My company will also employ without the cert III, it just restricts what you can/can't do
