         Re:      Registration Statement Under the Securities Act of 1933
                  -------------------------------------------------------

Ladies and Gentlemen:

         This opinion is rendered in connection with the Registration  Statement
on Form  S-3  filed  with the  Securities  and  Exchange  Commission  under  the
Securities Act of 1933, as amended,  (the "Act")  relating to the offer and sale
(the  "Offering")  of up to 116,800  shares of common stock,  par value $.10 per
share (the "Common Stock"),  of FSF Financial Corp. (the "Company").  As special
counsel to the Company,  we have  reviewed  such legal matters as we have deemed
appropriate for the purpose of rendering this opinion.

         Based on the foregoing, we are of the opinion that the shares of Common
Stock of the Company covered by the aforesaid  Registration Statement will, when
issued  in  accordance  with the  terms of the  Offering  against  full  payment
therefor,  be validly issued,  fully paid, and  non-assessable  shares of Common
Stock of the Company.

         We hereby  consent to the use of this  opinion and to the  reference to
our  firm  appearing  in the  Company's  Prospectus  under  the  heading  "Legal
Matters."  In giving  this  consent,  we do not admit  that we come  within  the
category of persons whose consent is required  under Section 7 of the Act or the
rules and  regulations of the Securities and Exchange  Commission  adopted under
the Act.

         This  opinion  is given as of the  effective  date of the  Registration
Statement  and we  assume  no  obligation  to  advise  you of  changes  that may
hereafter be brought to our attention.

                                        Sincerely,


                                        /s/Malizia Spidi & Fisch, PC
