在澳洲，移民政策一直是社會熱議的焦點，但近日的一場反移民遊行卻引發更深層的擔憂。上週日於墨爾本舉行的「反大規模移民」遊行，表面上看似是一場針對移民政策的抗議行動，實際上卻被極端主義勢力所滲透。參與其中的，不僅有部分普通民眾和政界人士，還出現公開宣揚白人民族主義的口號與符號，更有新納粹組織的成員混跡其中。

事件的焦點落在新納粹組織 National Socialist Network（NSN） 的頭目Thomas Sewell身上。Sewell是澳洲極右翼圈內廣為人知的人物，他長期鼓吹白人至上與「再移民」（remigration）等思想。這一概念主張將非白人移民驅逐出澳洲，其背後正是「白澳政策」時代的思想殘影。在遊行過程中，NSN的成員與其他極端分子一同現身，試圖藉由「反對大規模移民」這一社會議題，將新納粹及白人民族主義理念包裝成主流討論。

然而，警方並未坐視不管。在遊行結束後，Thomas Sewell於墨爾本被捕，消息立刻成為澳洲社會的焦點。這一逮捕行動，不僅突顯出當局對極端主義的警惕，也反映出當前移民議題的高度敏感性。儘管官方尚未公布具體指控內容，但Sewell 的拘捕意味著新納粹勢力在澳洲的活動已受到更嚴格的監視。

此次遊行之所以引發輿論關注，並不僅僅是因為「反移民」口號本身，而是它所折射出的更深層社會問題。一方面，澳洲社會對大規模移民帶來的房價壓力、基建負荷與文化衝突確有討論空間；另一方面，這些正當的政策辯論卻被極端主義團體所挪用，將之轉化為仇恨與分裂的工具。更令人擔憂的是，部分政客在言辭上似乎對這類遊行抱有「默許」甚至「暗中背書」的態度，無形中助長白人民族主義的聲量。

這場遊行因此被視為「白澳思想」的潛在回潮。所謂「白澳政策」，曾是澳洲歷史上長期推行的種族限制移民政策，其核心即是維護白人社會的單一性。雖然該政策早已廢除，但其思想餘毒仍不時浮現，而極端團體則樂於借當前社會矛盾來重提這一過時理念。

從此次事件來看，澳洲正處於一個微妙的十字路口：移民議題在公共政策討論中無法迴避，但社會必須警惕極端勢力將其劫持，進而撕裂多元文化社會的基礎。Thomas Sewell 的被捕，不只是單一人物的法律糾紛，更是一個警訊，提醒澳洲社會必須分清「合理的政策辯論」與「危險的極端主義」之間的界線。

In Australia, immigration policy has long been a topic of heated debate, but a recent anti-immigration rally has sparked deeper concerns. The protest, held last Sunday in Melbourne under the banner of opposing “mass immigration,” appeared on the surface to be a demonstration against government policy. In reality, however, it was infiltrated by extremist forces. Among the participants were not only ordinary citizens and certain political figures but also individuals openly promoting white nationalist slogans and symbols, with members of neo-Nazi groups blending into the crowd.

At the center of the controversy is Thomas Sewell, leader of the neo-Nazi organization National Socialist Network (NSN). Sewell is a well-known figure in Australia’s far-right scene, long advocating white supremacy and the concept of “remigration.” This idea calls for the expulsion of non-white immigrants from Australia, echoing the legacy of the old “White Australia Policy.” During the rally, NSN members and other extremists took advantage of the anti-mass immigration theme to repackage neo-Nazi and white nationalist ideas as part of mainstream political discourse.

The police, however, did not remain idle. After the rally, Thomas Sewell was arrested in Melbourne, immediately becoming the focus of public attention. The arrest not only underscores the authorities’ vigilance against extremism but also highlights the sensitivity of immigration issues today. While official charges have not yet been disclosed, Sewell’s detention suggests that neo-Nazi activities in Australia are under heightened scrutiny.

The significance of this rally lies not simply in its “anti-immigration” slogans but in the deeper social issues it reflects. On one hand, there is legitimate public debate about mass immigration and its impact on housing prices, infrastructure strain, and cultural tensions. On the other, these discussions have been exploited by extremist groups, turning them into tools for hatred and division. What makes the situation more troubling is that some politicians appear to show a degree of tacit approval—or even implicit endorsement—of such rallies, unintentionally amplifying the voice of white nationalism.

As a result, the protest is being viewed as a possible resurgence of the “White Australia” mentality. The White Australia Policy, once a cornerstone of Australian immigration law, aimed to preserve the country as a racially homogenous society. Although it has long been abolished, its ideological residue continues to resurface, with extremist groups eager to exploit current social tensions to resurrect this outdated notion.

Seen in this light, Australia stands at a delicate crossroads: immigration is an unavoidable issue in public policy, but society must remain vigilant against extremist forces hijacking the debate and undermining the foundation of multiculturalism. The arrest of Thomas Sewell is more than just a legal matter involving one individual—it is a warning that Australia must draw a clear line between legitimate policy debate and dangerous extremism.
