SAC 2MORROW: what is the difference between a treaty and an external affair

[Newton]

Please Sac is 2morrow, whats the difference between a treaty and an external affair???

[calcalcal30]

i'm pretty sure that under the external affairs section of the constitution (section 51 part xxix) the commonwealth has the power to make laws on anything that falls under a treaty they have entered into (exlcusive, concurrent and even residual)
