In Australia, many clubs arrange course-swap opportunities for their members. These come in various forms. Examples:
1. An annual swap day with another club (ie the memberships play the other club's course for that day);
2. A set allocation of mid-week comp spots for members of several other clubs (no visitor fees).
In Sydney, this is done every week between Royal Sydney, NSW GC, The Australian & The Lakes, so that members of all four clubs compete in each one's mid-week comp.
Some Melbourne do this as well (though not the most famous Melb clubs).
3. The Sandbelt group of clubs in Melbourne issue all members with a "Sandbelt Card", allowing one round per year at each of the other half-dozen clubs within the group (modest fee per round)
