@Rami check out
Liteshop (Massive range and best services in Aus) and
Olight Aus (Olight has an Australia Day Sale, but nothing overly bright beside one spotlight as the rest are small EDC torches). Both stores are run by the same guy, who is fantastic to deal with and constantly runs giveaways and sales, though Olight Global dictates their sales.
Flood = Higher lumens + Low Candela (Light Intensity) + shorter throw
Spotlight = Lower lumens + Higher Candela (light intensity) + longer throw
I prefer floodier torches, so a decent output 1000-1500+ lumens and 2-350m throw with an 18650, 21700 or 26650 battery (Bigger battery number typically better runtime, but a physically bigger torch
I like Lumintop, but the UI, Anduril, can be complicated and the torches themselves aren't brilliant for quality.
Olight is simple to use, 5-year warranty, magnetic charging, but typically only cool white LEDs which can wash out colour, but are brighter
Klarus is good, standard UI and quality build
Fenix is also good with a standard UI and quality build and range
Acebeam - standard UI and quality build
Nitecore - standard UI and quality build but can be pricey
Thrunite is good, cheaper than some but decent quality
Not a fan of Led Lenser personally, I don't like their zoom feature and preference for AA/AAA batteries
Rovyvon is a unique addition with interesting designs and features, but are not your typical torch if that's what you are chasing
Manker makes a solid light and they are well regarded
TL;DR - there are way too many options, figure out what you want and what your price range is
