Spouse visa 2.5y AUS Wife

Hi HNY to all and hope everybody is well and healthy.

I'm hoping to get some guidance on the following question regarding our situation.

I have checked previous posts,. Gov website and Citizens advice with no luck.

I'm a UK citizen and we live and work in the UK (2yrs now)
My wife (7yrs) is Australian on a Tier5 visa which runs out in April 2020
We are ready to submit and switch to a 2.5yr spouse visa.
With Brexit now set some news reports talk of an agreement with UK/AUS freedom of movement.

Prior to submitting thevisa applications is there any way to get information on if this UK/AUS deal will go ahead or safer to just submit as we intend to stay in the UK.

Many thanks for your time and advice.

It is only talk, nothing set in stone or even agreed or close to being agreed or negotiated.

Note that your spouse cannot stay in the UK once the current tier 5 visa expires
in the hope for this to come to light soon. These types of changes can take a long time.

Safer to switch visa now to avoid any overstay as periods of overstay will affect future citizenship application.

Many thanks for the fast reply and advice.
