Why not base the the electorates solely upon population i.e make each electorate have a base of N persons +/- M%?
The question is how to divide them up.
You need good demographic data.
In your chosen state you need to find the demographic centre. Hopefully down to at least a street or city blocks. This will be in the area of greatest population density. Note that is the number of people not voters.
Starting at that point you draw an area that encompasses N persons +/- M%. Follow streets, road, rivers etc. i.e. clearly visible boundaries. Then continue outwards from that first area aiming for N persons +/- M%. As the population density decreases the area of the electorate, division, district will increase. Continue until you reach the boundaries of your state.
The values of N, M will need to be massaged to suit. This is where computers will be most useful.
The boundaries should be reviewed to take account of shifting densities, population movements very regularly. In Australia after every state or commonwealth election the boundaries are reviewed. The minimum review would be at your census. You would expect that there would some changes at every review. Electorates will be added, decreased, boundaries shifted etc.
As an example I worked at the division called Gellibrand at our recent commonwealth election (2 weeks ago). This is the 3rd election I have worked in the same polling station in 2013, 2016, 2019. In 2013 the station was in the division called Lalor and the boundary was about 300m to the east. In 2016 the station was a dual division for Lalor/Gellibrand as the boundary was 2 streets away to the west. This election the station was in Gellibrand and the boundary was about 500m away to the west.
In 8 years the divisional western boundary moved about 800m. This was due to massive housing estates to the SW being built. Yet the number of electors has remained the same. The boundaries are changed to reflect the shifting population density. The division is actually moving westward.
Our review does not take in account how an area voted at previous elections. It is based solely upon population changes.
We have totally independent commissions at both state and commonwealth that are responsible to their parliaments, not the government of the day. Parties, parliament, voters etc can query the proposed new boundaries before they are promulgated.
The first cut is also the hardest. Once the rhythm is established it becomes simpler(?)
