Did a bit more digging...
"exim -d -bt simon@???" returns some useful info:
BTW, server hostname is server00.simonandkate.lan
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Testing simon@???
address match: subject=simon@??? pattern=*@localhost.localdomain
domain.net in "localhost.localdomain"? no (end of list)
simon@??? in "*@localhost.localdomain"? no (end of list)
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Considering simon@???

routing simon@???
--------> system_aliases router <--------
...
...cut to the result...
system_aliases router declined for simon@???
--------> userforward router <--------
local_part=simon domain=simonandkate.net
checking for local user
seeking password data for user "simon": cache not available
getpwnam () succeeded uid=xxx gid=xxx
calling userforward router
...
...
/home/simon/.forward does not exist
userforward router declined for simon@???
--------> procmail router <--------
etc
Last one is:
--------> localuser router <--------
this accepts it and files for local delivery.
This results for simon@ anything the same... ends up local delivered. So do I need to be calling the SMTP relay router before local user router? Is there a recommended order in which the routers should be called?
Should my SMTP relay be inserted after the system_aliases router but before the local routers?

Routers are tried in the order they are listed in your conf file. The
first to accept an address wins. Unless you have "unseen" set then no
more routers are tried for this address.

Yes, but make sure it doesn't catch domains for which you want local
delivery.
