Airport officials have revealed that throwing knives , samurai swords and even a grenade launcher were among the 300 illegal weapons seized at Perth Airport , in only the last two months . The deadly haul , brought into the country by passengers arriving in Australia , included flick knives , knuckle dusters and a crossbow . The grenade launcher , believed to be from Russia , was one of the more alarming finds . Heavily armed : Knuckle dusters , nunchuks and a grenade launcher were among the weapons seized from January 1 to March 4 . Figures released by the Australian Customs and Border Protection Service state that over 30 real and imitation firearms were seized from airline passengers . Passengers could face a $ 425,000 fine or 10 years in prison for importing dangerous goods without permission . Authorities say that people must be starting to understand these kinds of weapons wo n't be let into the country after they saw a drastic decrease in the number of weapons seized from 2013 to 2014 . Last year 1,318 illegal weapons were discovered , a significant drop from the 3,075 seized in 2013 . Assistant Minister for Imm­igration and Border Protection , Michaelia Cash , told Perth Now that it 's overseas vendors that are to blame for selling the weapons to Australians under the guise they will make it across the border . Authorities say Australians are being deceived by international vendors who lead them to believe the weapons will make it home . 'People may think that items such as laser pointers , flick knives , and shock devices make for an impressive souvenir but they could end up costing you more than you bargained for , ' Senator Cash said . She recommends that travellers make sure they understand the restrictions placed on what comes through customs so they do n't end up throwing their hard earned cash away . 'Every year , travellers are losing their hard-earned money by bringing items and gifts back into Australia that they ca n't keep . 'If you bring these things back they 'll be seized . You 'll lose the item , waste your money and may face a ­penalty . ' Airports are n't the only target with reports claiming firearms are being trafficked through the mail . In an annual report , by the Australian Customs and Border Protection Service , it was found that the number of undeclared handguns detected by customs had skyrocketed by 60 per cent . The report advised people are using the mail to conceal and deliver handguns in illicit firearm trafficking networks . Authorities maintain that identifying and dismantling these networks is a 'high priority ' . 'We have strengthened our targeting regimen and enhanced opportunities to increase detection of illicit firearms , ' the report said .
