Can I invest outside of market hours?
Yes, you can. However, your order will not be executed immediately.
When will my orders be placed?
Assuming you have enough funds, if you invest within market hours (10 am - 4 pm on ASX trading days), the order will be placed immediately. Otherwise, it will be queued and placed between 10:30 am - 11:30 am when the market re-opens.
What's the difference between queueing and placing an order?
Placing is when we submit an order to our brokerage partner. Queueing is an internal system that automatically places an order once you have enough cleared funds. You can queue multiple orders back-to-back and they will be handled in the order they were queued.
You also have the option to change when your queued orders get placed now. Activate and access the experimental feature here.

The same applies for US markets, which operate at different times
US market (NYSE/NASDAQ) are as follows:
-
1:30am - 8am (AEDT) during the wintertime (First Sunday in November to the fourth Sunday in March)
-
11.30pm - 6 am (AEDT) during the summertime (First Sunday in April to the fourth Sunday in October).
for US orders placed outside of US market hours it will be queued and placed once the US market opens.
