Awesome advice, thank you.
Additionally, I've found out that Uecomm has a community string of 10223:666 that will allow us to inject single /32's for null routing at their border.
Optus has confirmed that they only accept RFC1998 tags to 7474 and no others, but I think that if I use your advice and push tags out to Singtel 7473,and if I can bias Singtel traffic through to Uecomm, then I might be able to get nasty traffic to smash itself against the 7474 / 10223 border with a combination of the /32 injection, rather than coming down my links.
It would be nicer to block it futher out, but any port in a storm will do ;)
Cheers for all of the advice everyone, it's been exceptionally helpful.

Don't forget the upstreams. You could use RFC1998 tags but you may wish to signal Singtel rather than Optus, eg 7473:70. Not sure what Optus may do to your tags on ingress, but we've used it successfully in the past
