Legal frequencies in Australia

Hi there, I am intending to purchase the
Wireless Contact Closure Remote SPDT Relay Controller 2-Channel 1-Way.
The specs say it uses 900mhz.

In Australia the band we can use is limited to 915 to 928MHz.

Can this unit be set to the correct frequency in the 915 to 928MHz range.
Or is 900mhz OK to use for this purpose in Australia?

the 900mhz radio operate between 905-928mhz. the frequency can be limited between 915-928mzh using channel mask.
generally our production does that when they see an order shipping to UA region.
