Andrew Ready is still playing first grade for Easts in Brisbane this year. He could be a solid option for the tahs at hooker for a year or 2 if they've got young guys coming through who aren't quite ready to go yet, or the hopes of signing someone better who doesn't come off contract until '27. He's a bit of a gamble from a discipline perspective, but he's also a seasoned pro which there may not be too many of available if they're required to sign someone Australian qualified in the position by RA.
Alternatively Theo Fourie is turning out for the Reds in Tonga this weekend, but there's no chance the Reds are looking for another hooker so he'll be on the market. He was at the tahs last year so could be a solid option, but they'd want to be pretty confident in Dobbins as the number two. Fourie is realistically a (small) step down from him, particularly given Dobbins effectively replaced him at both the Rebels and the tahs. He is only 24 though, so could be a much longer term play than someone like Ready.
I still think Tom Horton would probably offer more than either of these guys though.
