Australian shares low value

Good afternoon

I have an estate with a small Australian shareholding. The shares are worth about £150. After discussing with brokers etc it seems that is would not be cost effective to sell, transfer these. I wondered if anybody could suggest what could be done in the circumstances. Should they simply be left? I am regularly receiving statements relating to the holding. There were several beneficiaries. Most of the estate admin has been concluded.

Please would you be able to provide your comments.
