If I was to be arrested, not being on any orders or any other charges, and was remanded in custody at my court appearance, and if I asked the judge if I was presumed innocent until proven guilty, would they agree and therefore have to release me on bail?
Everybody is presumed innocent.
That's not what bail is about.
In general and very simplified terms, to be on bail is to be at liberty
between the time of charging and the time of trial.
This liberty can be conditional ("bail conditions").
In WA, both the police and courts can grant bail.
Who does what depends on the offence and the facts and circumstances.
The criteria for bail (and any attached conditions) are really quite simple,
and boil down to three things:
- To ensure that you will actually turn up to court as and when required; and
- To ensure that you will not commit new or further offences in the time between arrest and trial.
(this can include interfering with witnesses or evidence); and
- To provide greater safety of the accused, safety of others (such as victims or survivors),
and safety of the community generally.
Bail is not a function of how likely it is that you are guilty of whatever it is that you are charged with.

this.
One other thing - Whatever offence you are contemplating,
that prompted you to ask your original question, don't commit it.
