Yes, you can withdraw your funds at any time using the withdrawal request feature:

Your investments are not subject to a minimum investment period, and there is no exit fee.

You should, however, always consider the suggested timeframe of your chosen model portfolio(s) and associated brokerage charges to sell your holdings.

The holdings are very liquid and trade as ETFs on the ASX.

We usually have funds returned to clients in 4-5 business days from the submitted withdrawal request. Withdrawal requests are processed the following day they're received.

If you have multiple model portfolios in your InvestSMART PMA you can choose which investment the funds are drawn from via the Withdrawal Request section.
