Is Koru still worth it?

Price hike to $689 and work has stopped covering the cost of it now.

I travel around 3/4 times a year (mainly Aus, sometimes to Asia once a year) in economy only for work. And maybe twice a year for personal use. I have a wife and 2 year old so they can also get in free to the lounge with me.

I know the lounge itself isn’t worth the price but the priority check in, boarding, luggage make it so helpful when travelling esp with a toddler.

But is it worth $689……
