Optus ipv6 is still next to non-existent from what I recall, even on home NBN networks. Even TPG/Vodafone are starting to roll it out, although it hasn’t reached the MVNOs like Kogan yet.
EDIT: They might be finally rolling out ipv6 on their network going by this whirlpool thread

My Telstra eSIM didn’t automatically enable IPv6, when my physical SIM did, but enabling it in the
telstra.wapAPN fixed it.Optus ipv6 is still next to non-existent from what I recall, even on home NBN networks. Even TPG/Vodafone are starting to roll it out, although it hasn’t reached the MVNOs like Kogan yet.
