Should my husband apply for the DTV visa and add me as a supported spouse instead of pursuing the elite visa?

Recommendations please,

Bit of a long post, but please bear with me,

Our original plan as I don't earn an income, I'm a suppted wife, was for me to apply for a five year elite visa and my husband will work FIFO and get a multiple entry tourist visa, so we can spend most of our time in Thailand, I would mostly stay in Thailand and hubby would fly in too on his rostered weeks off instead of flying back to Perth, now this new DTV visa is in effect, I'm wondering would he would be better off applying for that and me added as a supported spouse (we are legally married, married in Phuket legally), I've attached a picture of the clause I'm referring to, but bit unsure of how that bit works, I'm hoping we can do it this way as it's a hell of a lot cheaper than the elite visa,

Thanks in advance for any advice
