No they dont. There is a limit of $1.6m per person being transferred into a pension account.
Once the money is in the pension account, it can grow without limit.
Many smsf’s have multiple members, so can potentially have multiples of $1.6m in pension accounts.

The amount held in excess of what can be placed into a pension account can still be held in an accumulation account, with no limit on value.

The reasons given for trying to sell 2m shares in the closing auction make no sense to me.
