Hi Keana,
senior carer or health care assistant ? They seem to exclude each other!
I'm not aware of an online site for hiring here in Malta.
THe rate for the job will most certainly be near minimal wage here in Malta. That is around 5 /hour before taxes and social security. You will have to find an employer willing to apply for a work permit for you.
It seems that most carers from the Phillipines go through agents who do the formalities for them.
Cheers
Ricky
