Not sure if I am correct here but if they are using a /28 now to comply with the APNIC rules as per the below they would need to show use for 25% now (a /26) and within one year using a /25 (50% of address space).
Late to this party, but perhaps worth mentioning that there's no requirement to use RFC1918 space in your network plan. Add up your phones, printers, laptops, IP-enabled fridges, and bingo, you qualify. Quite some time ago a few people wrote up a description of options relating to IPv4 multi-homing. It's old, and it doesn't really touch address assignment or AS number assignment. It's from before "GSLB" was a thing, too. Might still be worth a read, though. http://www.ietf.org/rfc/rfc4116.txt Joe
