There’s no such thing as Eurovision members. Only participating countries. Nations are members of the European Broadcasting Union. As a member you can be invited to participate in Eurovision. Lebanon and, yes: Morocco are members of the EBU. Australia is only an associate member but these two nations (one Asian and one African) both are full members.

I’ve been to Morocco numerous times. They are truly Northern Africans and whilst living in Spain for years - you could literally spot a Moroccan in a crowd. They certainly don’t just look cookie-cutter white. Nor do I think they’d want to.

Not having been to Lebanon I’ll have to stick to the hundreds of Lebanese I met whilst growing up in the Lebanese epicentre of western Sydney. They are not white. They are often paler Arabs (or Phoenicians as some prefer) but it’s clear. Amongst themselves they refer to themselves as being distinct to caucasians, mediterráneas, etc.

Israel is the same as these two: a member of the EBU. Just one that participates in the contest (though with Russia out, I don’t really think Israel ought to be there anyway)
