Why people convert Santiago to Sydney time

Scheduling a call from Santiago to Sydney: a 10:00 AM start in Santiago lands at 11:00 PM in Sydney, so you can confirm the slot without doing the arithmetic yourself.
Handling a +13h gap: Santiago and Sydney have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Sydney is 10:00 PM in Santiago.
Coordinating a Santiago-based team with Sydney contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +13h gap is not.
With a +13h gap there is no shared 9-to-5 window, so alternate the early start: one week Santiago takes the early slot, the next week Sydney does.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the +13h gap.
Sydney: Clocks spring forward on Sat, Oct 3, 2026. Any meeting series spanning that date will shift by an hour in local time.
