(I believe Australia is the same way--liquids are fine on domestic flights, but must meet the 100mL requirement for international flights.)
AU has separate terminals at airports for domestic and international flights for this exact reason (a planespotter's nightmare, and operationally a pain since they have to tow the plane across the airport, or even runway, like at SYD, if they want to operate a domestic widebody service). Not liquids, but HNL has agriculture screening between concourses and at gates.
