Convertible Notes	Note 6 – Convertible Notes At December 31, 2011 and September 30, 2011, convertible notes payable amounted to $973,395 and $934,567, respectively, net of discounts of $195,042 and $143,871, respectively. The notes bear interest at 10% - 12% per annum, and are convertible into common stock of the Company at $0.15 - $0.25 per share (as well as variable conversion rates as described below). The notes are due at various dates through November, 2012 and are unsecured. Unsecured Convertible Notes: Through December 31, 2011, the Company issued $530,000 of convertible debentures (of which $152,500 is outstanding at December 31, 2011) that are convertible into common stock of the Company at variable conversion rates that provide a fixed rate of return to the note-holder. Under the terms of the notes, however, the Company could be required to issue additional shares of common stock in the event of default. The Company determined that the conversion option should be bifurcated from the notes and valued separately. This conversion option has been recorded as a derivative liability, is being amortized over the terms of the related notes, and is carried at fair value in the accompanying balance sheet. During the three months ended December 31, 2011 and December 31, 2010, the change in fair value of this derivative liability amounted to $325 and $(5,557), respectively. During the three months ended December 31, 2011, holders of convertible debentures elected to convert $90,000 of their debt plus accrued interest into 3,757,808 shares of common stock. 6% Convertible Redeemable Note: On November 23, 2011 Sionix issued a 6% Convertible Redeemable Note in the principal amount $100,000 maturing on November 23, 2012. Sionix has an optional right of redemption prior to maturity upon a five (5) day notice and payment of a 40% premium on the unpaid principal amount of the loan. Sionix paid fees of $15,000 in connection with the funding of this loan. In addition, the Company received a commitment in the form of a promissory note from the lender pursuant to which the lender will provide the Company with funding of up to an additional $300,000 at the Company's discretion beginning on June 1, 2012, at which time $100,000 will become available, on each of June 1, 2012, July 1, 2012 and August 1, 2012 (the "Additional Financing"). In conjunction with obtaining the Additional Financing, the Company issued 500,000 shares of common stock to the lender (the "Lender's Shares"). If the Company fails to draw down all of the funds made available by the Additional Financing between June 1, 2012 and August 1, 2012, the lender will be entitled to keep the Lender's Shares. If the Company draws down all of the funds made available by the Additional Financing between June 1, 2012 and August 1, 2012, the lender will use the Lender's Shares toward the conversion of the outstanding principal amount on the 6% Convertible Redeemable Note into shares of the Company's common stock. The conversion price for each share of common stock will be equal to 70% of the lowest closing bid price of the common stock for a period of five trading days, but no lower than $0.001 per share.
