Thank you for your interest in employment with BOOM Logistics.  As you reside outside of Australia and not currently living in Australia, I am afraid that it appears all occupations except crane operator & rigger appear on the National Visa listing.  Thus, we can not bring crane operators to Australia on a 457 visa sponsorship. See the link below for more information.

If we have miss understood your situation please proceed with submitting an Expression of Interest.  Should you gain your own work visa for Australia, please feel free contact us to see if we have any vacancies at that time.  Best wishes for your endeavours of coming to Australia.
