BoB - Eterna
Would give you access to all domestic lounges and even a few premium ones
Unlimited access for both primary and add-on card holders
Yearly fees is 3000 (roughly after tax)
Very good online reward rate and you can get waiver on annual fees with spends of 2L in a year
Personally i think it's a very good lounge card with (second) best online reward rate irrespective of merchant
